Question

Which contain a common ion that will shift the equilibrium system represented by the equation shown? Select all that apply. MgSO4 Na2S HNO3 CaCl2.

Answer 1

The compounds in the reaction that shifts the equilibrium with the common ion effect are $\rm MgSO_2\;and\;HNO_3$.

What is the common ion effect?

The equilibrium condition has an equal amount of reactant and products in the reaction.

The addition of ions same as product or reactant results in a change in the equilibrium of condition and shifts the equilibrium in opposite direction.

The given reaction is:

$\rm H_2SO_4\;\rightleftharpoons 2H^+\;+\;SO_4^{2-}$

The addition of sulfate and hydrogen ions shifts the equilibrium.

Thus, the compounds that shift the equilibrium for the reaction are $\rm MgSO_2\;and\;HNO_3$.
